Energy savings selector tool

ABSTRACT

An energy savings selector tool may assists a user in determining electrical devices that, when implemented in a load control system, may reduce an amount of power used by the load control system. The energy savings selector tool may use load control information of the load control system to identify electrical devices that may be added to or replace other electrical devices in the load control system. The load control information may define operations of the load control system and/or include energy usage information of the load control system. The energy savings selector tool may identify savings information associated with implementing an electrical device in the load control system. Once an electrical device is installed in the load control system, the energy savings selector tool may be used to report energy savings information about the electrical device.

BACKGROUND

In order to reduce energy consumption, consumers are increasinglyimplementing energy-saving devices in their load control environments,such as in the home, the office, and/or the like. These energy-savingdevices include both electrical loads and load control devices. Commonelectrical loads that are being implemented by consumers today areenergy-saving lighting loads. For example, the use of high-efficiencylight sources (e.g., gas discharge lamps, such as compact fluorescentlamps (CFL) and light-emitting diode (LED) light sources) is increasing,while the use of low-efficiency light sources (e.g., incandescent lampsor halogen lamps) is decreasing. Particularly, many consumers arereplacing older screw-in incandescent lamps with screw-inhigh-efficiency lamps to provide a quick path to reducing energyconsumption. Common electrical load control devices that are beingimplemented by consumers are electrical motorized window shades. Thesemotorized window shades help save energy by controlling the amount ofnatural light in a room, as well as the amount of heat that comes in orgoes out of the room.

As many energy-efficient devices are on the market, consumers may havedifficulty determining which devices to implement in their load controlenvironments. For example, many consumers may have difficultydetermining the load or load control device that may provide thegreatest cost savings in the shortest period of time. As such, it may bebeneficial to provide cost savings information associated withelectrical loads and/or load control devices, or other information thatmay assist a consumer in choosing the loads and/or load control devicesto implement in their load control environments.

Once an energy-efficient load or load control device has been installed,consumers often wonder if it was worth the price of purchase.Specifically, consumers are wondering if the energy-saving load or loadcontrol device is actually saving energy and/or cost and, if so, howmuch it is saving them. Thus, it would also be beneficial to provideafter-installation savings information to the consumer.

SUMMARY

As described herein, an energy savings selector tool may be used toassist a user in determining electrical devices that, when implementedin a load control system, may reduce an amount of power consumed by theload control system. The electrical devices may include one or moreelectrical loads and/or load control devices. The load control systemmay include electrical load control devices that are each configured tocontrol an amount of power provided to one or more electrical loads. Theelectrical devices may be replaced to reduce the amount of powerconsumed by the load control system. For example, a low-efficiency lightsource may be replaced with a high-efficiency light source.Additionally, or alternatively, electrical devices may be added to theload control system to reduce the amount of power consumed by the loadcontrol system. For example, an electrical motorized window treatmentmay be added to a load control system to allow natural light in a loadcontrol environment and reduce power consumed by lighting loads. Theenergy savings selector tool may be used to provide information toassist the user in selecting the electrical devices to be implemented inthe load control system.

The energy savings selector tool may provide information for recommendedelectrical devices for being implemented in the load control system. Forexample, the energy savings selector tool may provide savingsinformation associated with using one or more electrical devices in theload control system. The savings information may include projected costsavings information and/or payback information for using an electricaldevice in the load control system. The cost savings information mayinclude a projected amount a user may save by implementing therecommended electrical device in the load control system. The paybackinformation may include a projected amount of time to payback the costof the recommended electrical device based on the savings a user mayreceive from the use of the electrical device. The projected savingsinformation may be determined based on current usage of electricaldevices in the load control system.

The energy savings selector tool may provide information on electricaldevices that are currently implemented in the load control system. Forexample, the energy savings selector tool may provide savingsinformation for an electrical device after it has been installed and/orimplemented in the load control system, or within an otherwise definedtime period. The cost savings information may include the amount a userhas saved by implementing the electrical device in the load controlsystem. The payback information may include the amount of time left topayback the cost of the electrical device, the time it took to paybackthe cost of the electrical device, and/or the number of times theelectrical device has been paid back. The payback information may bebased on the savings a user may receive from the use of the electricaldevice. The savings information may be determined based on current usageof the electrical devices in the load control system.

The information provided by the energy savings selector tool may bebased on load control information associated with the load controlsystem and/or other relevant information that may be used fordetermining an electrical device for being implemented in the loadcontrol system. The load control information may include identificationinformation regarding the electrical loads and/or electrical loadcontrol devices in the load control system, association informationregarding the electrical loads and/or electrical load control devices,usage information associated with the electrical loads and/or electricalload control devices, an average amount of power associated with anelectrical load (e.g., which may be based on a number of electricalloads controlled by an electrical load control device, a load typeassociated with the electrical loads, and an intensity level associatedwith the electrical loads), and/or information regarding how the loadcontrol devices respond to inputs received from the input devices. Theenergy savings selector tool may access the load control information todetermine electrical devices for being implemented in the load controlsystem, determine the cost savings information, determine the paybackinformation, and/or provide other information that may be useful to theuser in determining electrical devices to implement in the load controlsystem. Other information that may be accessed by the energy savingsselector tool may include local energy rates for determining the cost ofthe energy, weather information, and/or GPS data.

The energy savings selector tool may be implemented on a single device,or distributed across multiple devices. For example, the energy savingsselector tool may be implemented on a network device (e.g., a personalcomputer, a smartphone, a tablet, etc.), a system controller device thatcollects information about the load control system, a remote computingdevice, or any combination thereof. The network device may provide auser interface for the user to access information provided by the energysavings selector tool. The information that is provided by the networkdevice may be generated locally, or received from the system controllerdevice and/or the remote computing device. If the information providedby the energy savings tool is generated at the network device, thenetwork device may access information from other sources, such as loadcontrol information that may be stored at the system controller device,or local energy rates or weather information that may be stored atanother remote source, for example.

The load control system 100 may comprise various electricaldevices. The electrical devices may include the electrical loads or theload control devices for controlling the amount of power provided to theelectrical loads. For example, the load control system 100 may include aload control device for controlling a lighting load, such as awall-mounted dimmer switch 110, coupled in series electrical connectionbetween the AC power source 102 and the lighting load, e.g., a lamp 112installed in a ceiling mounted downlight fixture 114. Alternatively, thelamp 112 may be installed in a wall-mounted lighting fixture or otherlighting fixture mounted to another surface. The dimmer switch 110 maybe adapted to be wall-mounted in an electrical wallbox.

The dimmer switch 110 may comprise a plurality of actuators 116 (e.g.,buttons) for controlling the lamp 112. In response to actuation of theactuators 116, the dimmer switch 110 may be configured to turn the lamp112 on and off, and to increase or decrease the amount of powerdelivered to the lamp and thus increase or decrease the intensity of thelamp from a minimum intensity (e.g., approximately 1%) to a maximumintensity (e.g., approximately 100%). The dimmer switch 110 may comprisea plurality of visual indicators 118, e.g., light-emitting diodes(LEDs), which may be arranged in a linear array and may be illuminatedto provide feedback of the intensity of the lamp 112. The dimmer switch110 may include a control circuit (e.g., a microprocessor or othersuitable processing device) that may respond to commands (e.g., from auser-operated device) that may be received via wired and/or wirelesscommunications. For example, the dimmer switch 110 may include a radiofrequency (RF) receiver that may receive the commands via an RF signal.Examples of wall-mounted dimmer switches are described in greater detailin U.S. Pat.

In response to inputsreceived via the GUI software, the network device 170 may build and/oredit the load control information stored in the system controller device160. The user may enter load control information and/or the load controlinformation may be received or obtained from another external source,such as via the network 162, for example.

The load control information may include a load schedule havinginformation regarding the different load control devices of the loadcontrol system 100 (e.g., the dimmer switch 110, the plug-in loadcontrol device 120, the motorized window treatment 180, and/or thetemperature control device 190) and/or the respective loads that may becontrolled by each load control device. The load schedule informationmay include identification information (e.g., unique identifiers, devicetype, etc.), association information (e.g., addresses and/oridentification information regarding associated devices forcommunication), configuration information (e.g., device communicationprotocols, device settings that may be enabled, etc.), and/or otherinformation about the load control devices and/or loads in the loadcontrol system 100. The load control information may include informationabout the electrical load and/or load control devices, such as lightinginformation for the lamps 112, 122, HVAC information for the HVAC thatmay be controlled by the temperature control device 190, and/ormotorized window treatment information for the motorized windowtreatment 180. The lighting information may include the number of lumensproduced by each lighting load of the load control system 100, or aportion thereof (e.g., a room, a floor, a group of floors, etc.). Thelighting information may include a number, type, and/or a power rating(e.g., wattage) of lamps that may be controlled by a respective loadcontrol device located in the load control system 100 or located in aportion of the load control system 100 (e.g., a room, a floor, a groupof floors, etc.). The HVAC information may include an HVAC efficiency, acooling capacity (e.g., in BTUs), a number of HVAC units, an HVAC unittype, and/or a power rating (e.g., a voltage, amps, etc.) for one ormore HVAC units that may be controlled by a respective load controldevice located in the load control system 100 or located in a portion ofthe load control system 100 (e.g., a room, a floor, a group of floors,etc.). The motorized window treatment information may include a numberof electrical motors or motorized window treatments, a type ofelectrical motor for one or more motorized window treatment, shadeand/or window dimensions for one or more motorized window treatment,and/or a power rating (e.g., a voltage, amps, etc.) of an electricalmotor for one or more motorized window treatments that may be controlledby a respective load control device located in the load control system100 or located in a portion of the load control system 100 (e.g., aroom, a floor, a group of floors, etc.).

The load control information (e.g., the load control database) mayinclude information regarding how the load control devices respond toinputs received from the input devices (e.g., the battery-powered remotecontrol device 130, the occupancy sensor 140, the daylight sensor 150,and/or the shadow sensor 152). For example, the load control informationmay indicate an adjusted dimming level (e.g., increase/decrease tenpercent, increase/decrease twenty percent, turn on/off, go to a presetlevel, etc.) for the dimmer switch 110 and/or the plug-in load controldevice 120 in response to commands from the input devices. The loadcontrol information may indicate an amount to adjust the coveringmaterial 182 (e.g., raise/lower ten percent, raise/lower twenty percent,fully raise/lower, go to a preset position, etc.) for the motorizedwindow treatment 180 in response to commands from the input devices. Theload control information may indicate an amount to adjust the setpointtemperature (e.g., raise/lower one degree, raise/lower five degrees, goto a preset temperature, etc.) for the temperature control device 190 inresponse to commands from the input devices. The load controlinformation may indicate a similar or a different response to commandsfrom different input devices. For example, the load control informationmay indicate that the dimmer switch 110 may adjust a dimming level ofthe lamp 112 by ten percent for each command from the battery-poweredremote control device 130, but turn on or off the lamp 112 for arespective occupancy or vacancy command from the occupancy sensor 140.

The system controller device 160 may be configured to transmit querymessages to the load control devices (e.g., the dimmer switch 110, theplug-in load control device 120, the motorized window treatment 180,and/or the temperature control device 190) to receive correspondingfeedback information from the load control devices. The feedbackinformation from the dimmer switch 110 or the plug-in load controldevice 120 may include the corresponding intensity level at which thedimmer switch 110 or the plug-in load control device 120 are controllingpower to the respective lamps 112, 122 and/or the measured power fromthe load control device. The feedback information from the motorizedwindow treatment 180 may indicate a level or setting at which thecovering material 182 is set. The feedback information from thetemperature control device 190 may indicate the setpoint temperature atwhich the temperature control device 190 is set for controlling the HVACsystem and/or a current room temperature.

The system controller device 160 may be configured to calculate theamount of energy consumed by and/or saved by the use of each electricaldevice in the load control system 100. The system controller device 160may measure the length of time that each load control device isproviding power to an electrical load. For lighting control devices, thesystem controller device 160 may also know the intensity level at whichthe power is provided for the measured period of time. The systemcontroller device 160 may be configured to store a historical record ofthe power usage, which may include a historical record of power providedto one or more electrical loads by load control devices over a period oftime. For lighting control devices, the historical record of power usagemay include the intensity level at which power may be provided to theload control devices and may include the corresponding time that theload control device was operating one or more electrical loads at thatintensity level in memory. The system controller device 160 may beconfigured to determine the average power consumed by the loadscontrolled by each of the load control devices over a period of time,for example, using the historical record of power usage, the number, thetype, and/or the power (e.g., watts, volts, amps, etc.) of theelectrical load (e.g., lamp 112, lamp 122, HVAC unit, electrical motorof the motorized window treatment 180, etc.) controlled by therespective load control device (e.g., the dimmer switch 110, the plug-inload control device 120, the motorized window treatment 180, thetemperature control device 190, etc.).

The system controller device 160 may be configured to predict the amountof energy that may be saved by the use of a recommended electricaldevice. In addition, the system controller device 160 may be configuredto measure the amount of energy that may be saved by the use of therecommended electrical device after installation. The recommendedelectrical device may include any electrical load and/or electrical loadcontrol device.

The predicted amount of energy savings may be based on the replacementor addition of an electrical load, such as the replacement of a lightingload or the addition of an electrical motor in a motorized windowtreatment, for example. The system controller device 160 may beconfigured to measure the amount of energy that may be saved by usinghigher-efficiency light sources for the lamps 112, 122 that may consumeless power. Before the higher-efficiency lamps 112, 122 are installed,the system controller device 160 may be configured to calculate aprojected energy savings if the higher-efficiency lamps 112, 122 areinstalled in the load control system as compared to lower-efficiencylight sources that may consume more power. The projected energy savingsmay be based on a current consumption of power by lower-efficiency lightsources in the load control system 100 and a projected reduction inusage after installing the higher-efficiency lamps 112, 122 that mayconsume less power. The system controller device 160 may also, oralternatively, calculate the actual energy savings based on the use ofthe higher-efficiency lamps 112, 122 after being installed in the loadcontrol system 100. The savings after installation may be based on theconsumption of power by the lower-efficiency lamps in the load controlsystem 100 before installing the higher-efficiency lamps 112, 122 andthe consumption of power by the higher-efficiency lamps 112, 122 afterinstallation.

The predicted amount of energy savings may be based on the replacementor addition of a load control device, such as the replacement oraddition of a temperature control device or a motorized windowtreatment, for example. The system controller device 160 may beconfigured to measure the amount of energy that may be saved by the useof the motorized window treatment 180 before the motorized windowtreatment 180 is installed. The motorized window treatment 180 may raisethe covering material 182 to allow natural light or external heat intothe space in which the load control system 100 may be installed. Themotorized window treatment 180 may lower the covering material 182 toprevent natural light from entering, or prevent heat from entering orescaping from, the space in which the load control system 100 may beinstalled. The raising or lowering of the covering material 182 mayallow a load control device (e.g., the dimmer switch 110, the plug-inload control device 120, the temperature control device 190, etc.) toreduce the amount of energy used for controlling the respective loads(e.g., the lamp 112, the lamp 122, the HVAC system, etc.). For example,the raising of the covering material 182 may allow the dimmer switch 110to reduce the intensity level of the power provided to the lamp 112 dueto the natural light, and/or allow the temperature control device 190 toprovide power to the HVAC system less often due to the heat from thenatural light.

The system controller device 160 may be configured to measure the amountof energy that may be saved by using the motorized window treatment 180.Before the motorized window treatment 180 is installed, the systemcontroller device 160 may be configured to calculate a projected energysavings if the motorized window treatment is installed in the loadcontrol system as compared to when the motorized window treatment is notinstalled. The projected energy savings may be based on a currentconsumption of power by electrical loads in the load control system 100and a projected reduction in usage after installing the motorized windowtreatment 180. The system controller device 160 may also, oralternatively, calculate the actual energy savings based on the use ofthe motorized window treatment 180 after being installed in the loadcontrol system 100. The savings after installation may be based on theconsumption of power by the electrical loads in the load control system100 before installing the motorized window treatment 180 and theconsumption of power by the electrical loads after installing themotorized window treatment 180.

The load control device may be an input device, such as the occupancysensor 140 or other sensing device, for example. The system controllerdevice 160 may be configured to measure the amount of energy that may besaved by the use of the occupancy sensor 140 before the occupancy sensor140 is installed. The occupancy sensor 140 may detect the occupancy orvacancy of a space in the load control environment and may sendinstructions to the load control devices for controlling an electricalload. The control of the electrical loads based on occupancy may save onthe energy consumed by the load control system, as the electrical loads(e.g., lighting loads, HVAC systems, etc.) may consume less power when aroom is unoccupied. Other input devices (e.g., the battery-poweredremote control device 130, the daylight sensor 150, the shadow sensor152, etc.) may similarly be used to save on the amount of energyconsumed by the load control system. The battery powered remote controldevice 130 may save on the amount of energy consumed, as the remotecontrol device 130 may make the amount of power consumed by anelectrical load (e.g., lighting loads, HVAC systems, etc.) easier tochange. The daylight sensor 150 and/or the shadow sensor 152 may save onthe amount of energy consumed, as electrical loads (e.g., lightingloads, HVAC systems, etc.) in the load control system may consume lesspower when more natural light is being received in a space.

Before an input device is installed, the system controller device 160may be configured to calculate a projected energy savings if the inputdevice is installed in the load control system as compared to when theinput device is not installed. The projected energy savings may be basedon a current consumption of power by electrical loads in the loadcontrol system 100 and a projected reduction in usage after installingthe input device. The system controller device 160 may also, oralternatively, calculate the actual energy savings based on the use ofthe input device after being installed in the load control system 100.The savings after installation may be based on the consumption of powerby the electrical loads in the load control system 100 before installingthe input device and the consumption of power by the electrical loadsafter installing the input device. Though the examples described hereinmay calculate the energy savings for use of a lighting load, a motorizedwindow treatment, and various input devices, energy savings may besimilarly calculated based on the addition or replacement of any otherelectrical device, such as any electrical load or any load controldevice.

The projected energy savings for an electrical device may be calculatedbased on the historical record of power usage for other load controlsystems. For example, the system controller device 160 may compare thehistorical record of power usage for the load control system 100 againsta historical record of power usage for similar load control systems thatinclude recommended electrical devices. A similar load control systemmay include a similar number of loads and/or load control devices,similar types of loads and/or load control devices, and/or a similarconfiguration of the load control system. The number of loads and/orload control devices in a similar load control system may vary by apredetermined number.

The system controller device 160 may perform the comparison locally orsend, via the network 162 for example, the historical record of powerusage to an external computing device and may receive, via the network162, comparable power usage information for a load control system thatalso includes the recommended electrical devices to determine thesavings when the recommended or installed electrical devices areimplemented. The system controller device 160 may send, via the network162, the average power consumed by the loads of each of the load controldevices over a period of time, the average amount of time each of theloads is energized over a period of time, the types of loads and/or loadcontrol devices in the load control system, and/or the historical recordof the load control devices to an external computing entity and mayreceive, via the network 162, the projected savings. The systemcontroller device 160 may store the projected energy savings and mayprovide them to the user via the network device 170. The projectedenergy savings may be used to recommend electrical devices that may beinstalled.

After an electrical device is installed, the system controller device160 may store the power consumed by the loads controlled by each of theload control devices. The system controller device 160 may keep ahistorical record of power usage after the electrical device isimplemented. The system controller device 160 may perform a comparisonof power usage information that was tracked before the implementation ofthe electrical device with the power usage information tracked afterimplementation to determine the savings after implementation of theelectrical device. The system controller device 160 may also send thepower usage information to an external device, via the network 162 forexample, which may perform the comparison and send the savingsinformation back to the system controller device 160. The savings afterimplementation may be provided to the network device 170 for display toa user. The user may also receive savings information within a definedtime period after installation (e.g., each month, each year, etc.),which may be stored at the system controller device 160, and/ordetermined (e.g., by the system controller device 160, the networkdevice 170, or another device) from the power usage information storedat the system controller device 160.

The GUI software running on the network device 170, or otherwiseprovided to the network device 170 via the network 162, may provide aninterface for an energy savings selector tool to display information tothe user on the network device 170. The energy savings selector tool mayinclude options that may assist the user in determining electricaldevices of the load control system that may be added or replaced to saveenergy. For example, the energy savings selector tool may indicate whichof the low-efficiency light sources (e.g., the lamps 112, 122) of theload control system may be replaced with high-efficiency light sources(e.g., screw-in LED lamps). The energy savings selector tool may also,or alternatively, indicate that the load control system may save onenergy usage with the replacement of one or more loads (e.g.,high-efficiency lamps), the replacement of one or more load controldevices (e.g., improved dimmer switches), the addition of one or moreloads, and/or the addition of one or more load control devices (e.g.,motorized window treatment 180 and/or the occupancy sensor 140).

The energy savings selector tool may provide savings information thatmay indicate the amount of savings that may be accrued or that hasaccrued as a result of using a recommended electrical device. Thesavings information may include cost savings information and/or paybackinformation for the electrical device options that are provided. Forexample, the energy savings selector tool may indicate the lamp optionsthat may result in the greatest cost savings and/or shortest paybacktime period. The energy savings selector tool may access the loadcontrol information (e.g., the number, type, and/or power rating of theelectrical loads controlled by the respective load control devices)stored by the system controller device 160. The load control informationmay include the usage information for the electrical devices in the loadcontrol system 100. The usage information may indicate the average powerconsumed by each of the loads controlled by the load control devices, anaverage amount of time each of the loads is energized, and/or thehistorical record of power usage over a period of time. The usageinformation may be determined based on the number, type, and/or powerrating of the electrical loads controlled by a load control device. Whenthe electrical load is a lighting load, the load control information mayinclude the number, type, wattage, and/or lumen output of the lightingload.

The energy savings selector tool may be configured to access electricaldevice information for electrical devices, such as electrical loadsand/or load control devices, that may be purchased to increase theenergy efficiency and/or decrease the energy costs of the load controlsystem 100. For example, the energy savings selector tool may beconfigured to access and/or display lamp information (e.g., a lampdatabase) regarding one or more high-efficiency light sources that maybe available for purchase from one or more manufacturers. The energysavings selector tool may be configured to access and/or displaymotorized window treatment information and/or covering materialinformation (e.g., a motorized window treatment and/or covering materialdatabase) regarding one or more window treatments and/or coveringmaterials that may be available for purchase from one or moremanufacturers. The energy savings selector tool may be configured toaccess and/or display input device information (e.g., a sensor database)regarding one or more input devices that may be available for purchasefrom one or more manufacturers. The electrical device information may bestored on the network device 170, the system controller device 160,and/or an external computing device that may be accessed via the network162.

The energy savings selector tool may have access to energy and/orweather information at the location in which the load control system 100may be installed. For example, the energy savings selector tool mayaccess local energy rates at the location in which the load controlsystem 100 may be installed. The energy savings selector tool may beconfigured to receive peak and/or off-peak energy rates that correspondto different time periods of a day. The energy savings selector tool mayaccess weather information at the location in which the load controlsystem 100 may be installed to assist in determining a current orexpected amount of sunlight, an amount of cloud cover, and/or an outsidetemperature. The local energy rates and/or weather information may beentered into the energy savings selector tool manually by a user or maybe accessed automatically (e.g., using a GPS location of the networkdevice 170 or the load control system 100). The energy savings selectortool may retrieve the local energy rates and/or weather information viathe network 162. For example, the local energy rates may be retrievedfrom an electrical utility company and/or the local weather informationmay be retrieved from a weather provider.

The energy savings selector tool may use the load control information(e.g., the usage information) in the system controller device 160, theelectrical device information, the local energy rates, the local weatherinformation, GPS information, time of day information, time of yearinformation, and/or information from the input devices (e.g., daylightsensor 150, shadow sensor 152, etc.) to determine one or more electricaldevices that may be implemented in the load control system 100 toprovide a cost savings and/or a payback time period for the cost of theitems that may be purchased. For example, the energy savings selectortool may use the usage information stored in the load controlinformation (e.g., load control database), lamp information, and/or thelocal energy rates to determine one or more high-efficiency lightsources that may replace low-efficiency light sources (e.g.,presently-installed low-efficiency light sources) to provide the costsavings and/or payback time period. The energy savings selector tool mayuse the lumen output of the low-efficiency light sources (e.g.,previously-installed low-efficiency light sources) to choosehigh-efficiency light sources having equivalent or similar outputs. Theenergy savings selector tool may use the usage information stored in theload control information (e.g., load control database), motorized windowtreatment information, local weather information, and/or time of yearinformation to determine the cost savings and/or payback time period if,for example, a motorized window treatment is installed.

The energy savings selector tool may use the usage information of thedimmer switch 110 and the plug-in load control device 120 forcontrolling respective lamps 112, 122, the usage information of thetemperature control device 190 for controlling the HVAC system and/orthe local energy rates to determine an electrical cost for the loadcontrol environment. The energy savings selector tool may project asavings, such as an energy savings or a cost savings, that may indicatean amount a user may save if the user installed and/or implemented arecommended electrical device, such as high-efficiency light sources(e.g., the lamps 112, 122), the motorized window treatment 180, an inputdevice (e.g., the remote control device 130, the occupancy sensor 140,the daylight sensor 150, the shadow sensor 152, etc.), or anotherelectrical device.

The projected savings may be based on the amount of power saved by usingthe recommended electrical device. For example, the amount of savingsmay include the difference in power consumed by the low-efficiency lampsand the high-efficiency lamps. When a motorized window treatment isrecommended or installed, the amount of savings may include the reducedamount of power that may be provided to the lamps 112, 122 and/or theamount of power provided to the HVAC system as a result of theimplementation of the motorized window treatment 180. When a sensingdevice (e.g., the occupancy sensor 140, the daylight sensor 150, theshadow sensor 152, etc.) is recommended or installed, the amount ofsavings may include the reduced amount of power that may be provided tothe lamps 112, 122 and/or the amount of power provided to the HVACsystem as a result of the implementation of the sensing device. Thoughthe examples described herein may calculate the savings for use of alighting load, a motorized window treatment, and a sensing device, thesavings may be similarly calculated for any other electrical device thatmay be used in a load control system, such as any electrical load or anyload control device.

The anticipated savings, such as energy savings or cost savings, may bebased on similar load control environments that have similar electricaldevices installed therein. The projected savings may take into accountthe local energy rates, the local weather information, time of dayand/or time of year information, information collected from the daylightsensor 150 regarding the average amount of light in the load controlenvironment 100, information collected from the shadow sensor 152regarding the average amount of direct sunlight received from outsidethe load control environment, and/or information regarding any currentlyinstalled electrical devices. The energy savings selector tool mayprovide the cost information and/or the projected savings for one ormore electrical devices to give the user purchasing options. Forexample, the energy savings selector tool may provide the costinformation and/or the projected savings if a motorized window treatmentis installed, or for one or more types of high-efficiency lamps that mayreplace one or more low-efficiency lamps in a load control environment.

The energy savings selector tool may provide the cost information and/orprojected savings for materials or devices associated with theelectrical devices as well. For example, the energy savings selectortool may provide cost information and/or projected savings informationfor one or more covering materials that may be installed in a motorizedwindow treatment. Different materials may allow different amounts oflight into the load control environment and may have a different effecton the amount of savings that may result from using the coveringmaterial. Based on the amount of savings that may result from using anelectrical device or materials associated with an electrical device, theenergy savings selector tool may provide the projected payback timeperiod for paying back the cost of the electrical device or materialsassociated with an electrical device.

The energy savings selector tool may inform the user if another item isneeded or used with the recommended electrical device. For example, whenthe energy savings selector tool recommends a high-efficiency lamp thatmay replace a low-efficiency lamp, the energy savings selector tool mayalso recommend another dimmer switch and/or lighting ballast that may bedesigned to work with high-efficiency lamps. The energy savings selectortool may inform the user if another load control device is needed orused to control the recommended loads for purchase. The energy savingsselector tool may inform the user if another load is used with therecommended load control device. The energy savings selector tool mayuse the cost of the additional items when determining the payback timeperiod.

The energy savings selector tool may be executed by the systemcontroller device 160, the network device 170, and/or a remote computingdevice or server (e.g., on the cloud). The system controller device 160may be located in the load control system 100, or may be locatedremotely and may send information to devices in the load control system100. The energy savings selector tool may be executed at the systemcontroller device 160 or another remote computing device and may provideinformation to a user interface on the network device 170. In anotherexample, the energy savings selector tool may be executed at the networkdevice 170 and may access information, such as load control informationfor example, at the system controller device 160, another remotecomputing device, and/or another source. The energy savings selectortool may be executed at the system controller device 160, the remotecomputing device, or the network device 170 individually, or the energysavings selector tool may be distributed across one or more of theseand/or other devices.

FIG. 2 is an example screenshot of a user interface 200 that may bedisplayed by the energy savings selector tool on the visual display 172of the network device 170. The user interface 200 may be provided in theform of a load selector table, as shown in FIG. 2, or other format toprovide the information to the user of the network device 170. The userinterface 200 may include electrical device information 202. Theelectrical device information 202 may include identifiers of electricaldevices, such as electrical loads and/or load control devices that maycontrol a load. The identifiers may identify types of loads and/or loadcontrol devices. The identifiers may identify the various zones in whichthe loads and/or load control devices may be located in the load controlsystem 100 (e.g., as may be stored in the control information in thesystem controller device 160). As shown in FIG. 2, the electrical deviceinformation 202 includes a porch light, kitchen downlights, a livingroom lamp, a hallway downlight, a kitchen window treatment, and a livingroom occupancy sensor, though other types of electrical devices may beidentified.

The user interface 200 may include usage information 204 that mayindicate the amount of time that each of the identified electricaldevices is used. The usage information 204 may also, or alternatively,indicate the amount of power consumed by the electrical devices (notshown). For example, the usage information 204 may indicate an amount oftime that an electrical load is energized or an amount of power consumedby the electrical load. The usage information 204 may be determined fromthe usage information that may be stored by the system controller device160 or other device.

The user interface 200 may include savings information. The savingsinformation may include energy savings information (not shown), costsavings information 206, and/or payback information 208. The costsavings information 206 may indicate the respective cost savings foreach of the identified electrical devices. The cost savings information206 may be indicated in any increment of time, such as per week savings,per month savings, or per year savings, for example. The paybackinformation 208 may indicate the respective payback time period for eachof the identified electrical devices. The payback information 208 mayindicate the amount of time left to pay back the cost of one or moreelectrical devices, as shown in FIG. 2.

The savings information mayalso, or alternatively, include energy savings information that mayindicate the amount of energy (e.g., in units) that may be saved or thatis being saved by an electrical device.

The payback information 208 may be based on the cost savings information206 and/or the usage information 204. For example, the paybackinformation 208 may indicate the respective payback time period for oneor more low-efficiency light sources (e.g., presently-installedlow-efficiency light sources) when they are replaced with selectedhigh-efficiency light sources (e.g., as determined by the energy savingsselector tool).
